Title: Rocket braking device activated by explosive charge - and disc covering braking rocket blown out by explosion
Inventor: LUSCAN
IPC: F02K9/92
Filed: 1975-01-29
Abstract: The device is intended to brake a rocket propelled vehicle by bringing a secondary rocket into action which exerts a thrust in the opposite direction.

Title: Electrically driven screw jack - has reversing switch operated through spring device when load on screw exceeds preset value
IPC: H01H35/00
Filed: 1975-02-06
Abstract: An electrically driven screw jack has an electric motor mounted on a frame and driving a screw which engages a nut. The nut slides in guides which prevent rotation and carries a rectangular frame housing two compression springs (6) and (7) separated by a bar (8). The bar (8) is joined to a cable (9) which transmits the sliding motion of the nut to the driven equipment. A motor reversal switch (14) mounted on the frame (5) is actuated by stops (15)(16) at each end of the stroke. If a predetermined load on the cables (9) is exceeded the bar (8) compresses a spring, allowing a corresponding lug (11, 12) at the end of the cross bar at the end of the bar (8) to open the switch (13) and stop the motor (1).

Title: Stabilising halogenated solvents against water hydrolysis - using diboric ester of diethanolamine or polymer thereof
IPC: C07C17/42
Filed: 1975-02-27
Abstract: Halogenated solvents are stabilised by adding to the solvent 0.05-5% of the diester of boric acid with diethanolamine. The diester may be a monomer or a cyclic polymer of formula NH (CH2CH2O)2 BOH n where n is 1-6 or a linear polymer of formula H OCH2CH2NHCH2CH2OB-(OH)-OCH2CH2-NH-CH2CH2-OB(OH)- m CH where m is 1-10. Numerous halogenated organic solvents are unstable to water, hydrolysing to HCl which catalyses further reaction. These solvents, such as monofluorotrichloromethane are used as aerosol propellents. They are also used as cleaning solvents, refrigerants and as metal degreasants. The above stabilisers are odourless, compatible with perfumes and propellents and prevent corrosion resulting from acid formed. Pref. solvents are monofluorotrichloromethane, trichloroethylene, perchloroethylene and mixtures contg. these. The pref. quantity used is 0.2-0.5 pts. diester per pt. of water present.

Title: High free carrier transit time transistor - has emitter base input and base collector output
Inventor: GREMILLET JACQUES
IPC: H01L29/73
Filed: 1975-07-11
Abstract: A transistor having a high free carrier transit time for use in amplifier and binary circuits, consists basically of an 'N' doped emitter layer laid over a 'P' doped base. This overlays the collector which is also doped with 'N' type impurities, itself providing a further junction with a N+ layer. The dimensions are chosen such that the product of the free carrier time 'T' and the pulse rate frequency is greater than 1/2 pi. Such a transistor working at 46 Hz has an 18 microns thick collector with a doping level of 1014/cm3 and a limiting voltage of 45 volts working in a negative resistance mode, ie. having a 1.5 pi transit angle.

Title: Attachment of flexible trim materials - using longitudinal insert to trap material in grooved edge of support
IPC: F16B5/06
Filed: 1975-07-11
Abstract: A long insert (6) retains the sheet material (7) in the C-shaped section of the support (1). The insert is itself C-shaped having one long (8) and one short (9) flange, joined by a bent web (10). The short flange is curved inwards towards the long flange as is that (4) of the support edge towards its corresponding web (5). The width of the insert across the flanges (8, 9) is made at least equal to the minimum inside gap between the support flange and web (4, 5), the insert retaining the flexible material when assembled. The material (7) is placed in position across the support section and pressed down into the groove by the short flange (9) of the insert. The latter is then rotated until its long flange comes up against the web (5) of the support.

Title: Casting machines using endless belt of mould segments - exerting high pressure on melt during solidification of strip or bars (BE070177)
Inventor: BOCCON-GIBOD R
IPC: B22D11/06
Filed: 1975-07-08
Abstract: Process for continuous casting metal alloys such as strip, plate, bar, wire rod, ingots, etc. The melt is fed into a gap between a rotating casting wheel and a continuous row of moving mould segments forming a curved mould cavity. A high press. is exerted on the melt during solidification so the cast product is much thinner than the initial mould gap. The mould sides are formed by cooled segments which are mounted on swivels or can be retracted. Ti, Zr, Be and other special metals can be cast by melting consumable electrodes. Uses include casting Al round Cu or steel bars to make cables; casting metal round mesh or tubes to make composite sheet or tube walls for heat exchangers. The high press. exerted during solidification provides hot deformation which removes piping, segregation and shrinkage porosity in the cast products.

Title: Air cooled two stroke engine - has linkage connecting throttle to hinged sprung flap lifted by air from fan
IPC: F02B75/02
Filed: 1975-07-18
Abstract: The air-cooled, two-stroke engine (1) has a carburettor (2) with a throttle (3) connected by a link (9) to a hinged flap (6). An adjustable tension spring (10) pulls the flap (6) down over the cooling fins (7). A centrifugal fan (4) with curved blades (5) mounted on the crank-shaft directs a stream of cooling air against the flap (6). The pressure of the air lifts the flap (6) against the force of the spring (9), and actuates the throttle (3) so that the engine speed is reduced. The flap (6) thus acts as a speed governor and at the same time controls the flow of air over the cooling fins (7), through the gap (8) to the region between cylinder block and exhaust (11).

Title: Oxidn. device for purificn. of sewage - with elliptical disc with blades fitted to vertical rotating shaft
IPC: B01F3/04
Filed: 1975-12-19
Abstract: The oxidn. device consists of a vertical rotating shaft fitted at its lower end with a hub and a disc this has an elliptical surface, directed upwards with the shape of an inverted mushroom. Openings are provided for the passage of water and each opening has a bent elbow. Two rows of blades are fixed in the lower face of the body of the disc and co-operate with the bent elbows. The effect is to scatter the water into a number of clusters of jets the water is pulverises and the contact surfaces between the molecules of the water and the molecules of the air increased. The parabolic trajectory of the jets increases the contact time and improves the degree of oxidn. of the effluent. The device allows the water to absorb the max. amt. of oxygen and so improves the activated sludge process whilst shortening the treatment time.
